Australian Soil and Landscape Grid Pedogenon Maps at 3 Arc-Second Resolution

1950-2022 modelled estimates of Pedogenon soil classes across Australia. The map provides a 3 arc-second (approximately 90-meter) resolution raster with over 2 billion pixels, produced by the Terrestrial Ecosystem Research Network. It is designed to assess soil change using a space-for-time substitution approach.

Use Cases

• Assessing past soil change based on the space-for-time substitution approach described.
• Stratifying landscapes into homogeneous environmental variable groups for soil property analysis.
• Modeling anthropogenic pressure on soils using the pedogenon-to-pedophenon gradient concept.

Strengths

• Spatial resolution of 3 arc seconds (approximately 90 meters).
• Temporal coverage spans over 70 years from 1950 to 2022.
• Number of pixels with coverage per layer is 2007M (49200 * 40800).
• Data adheres to GlobalSoilMap specifications.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
